Are electromagnetic fields harmful to health?
There is some indication of a link between long-term mobile phone use and a benign tumour of the auditory nerve, but more study is needed. However, no link has been found between the use of such phones and self-reported symptoms like headaches, fatigue, or concentration difficulties. These are some of the conclusions of a recent opinion by the European Commission Scientific Committee on Emerging and Newly Identified Health Risks (SCENIHR).
At the request of the European Commission DG Health and Consumers, GreenFacts faithfully summarised this new scientific opinion on “Possible effects of Electromagnetic Fields (EMF) on Human Health”. The plain-language summary is now available from the EU Directorate General of Health and Consumers (http://ec.europa.eu/health/opinions2/en/electromagnetic-fields/(s’ouvre dans une nouvelle fenêtre)) in four languages: English, French, Spanish and German. It is also available from GreenFacts (http://www.greenfacts.org(s’ouvre dans une nouvelle fenêtre)) a leading publisher of scientific information that was commissioned by the Directorate General to produce this and other summaries of scientific opinions.
Highlights of the SCENIHR Opinion
For many of the possible health effects of electromagnetic fields, the data available are still very limited, especially for long-term low-level exposure.
The opinion looks at electromagnetic fields in different frequency ranges: radio frequencies such as those used in mobile telephony, intermediate frequencies like those from computer screens and anti-theft devices, and extremely low frequencies like those from power lines and household appliances. Moreover it addresses static magnetic fields like those used in medical imaging.
* New scientific evidence does not call for a revision of the exposure limits to radio frequency fields such as those used in mobile telephony.
* Possible health effects from long-term exposure to intermediate frequency should be properly assessed because exposure to such fields is increasing due to new technologies.
* The past conclusion that extremely low frequency magnetic fields are possibly carcinogenic is still valid. Indeed epidemiological studies indicated that children exposed to relatively strong magnetic fields from power lines were more likely to develop leukaemia, but this has not been confirmed or explained by experiments on animals and cell cultures.
* New applications of strong static magnetic fields – such as MRI scanners used in medical imaging – will require risk assessments for people who use the new technology at work.
How electromagnetic fields may affect animals and plants is insufficiently known to determine whether a single exposure standard would be appropriate for all plants and animals and whether such a standard should differ from those established for humans. Some animal species, such as migratory birds that rely on magnetic fields for orientation, might be particularly sensitive to electromagnetic fields.
About SCENIHR
The Scientific Committee on Emerging and Newly Identified Health Risks (SCENIHR) was set up in 2004 by the European Commission to provide the Commission with unambiguous scientific advice on the safety of a series of issues requiring a comprehensive assessment of the risks, such as new technologies, medical devices, etc. The SCENIHR advice is intended to enable risk managers to take the adequate and required actions in order to guarantee consumer safety or public health.
The SCENIHR addresses questions concerning emerging or newly-identified risks and on broad, complex or multi-disciplinary issues such as Variant Creutzfeldt-Jakob Disease, bovine spongiform encephalopathy (BSE), West Nile Virus, Nanotechnologies, Electromagnetic Fields (EMF), and Smokeless tobacco products.
About DG Health and Consumers
The role of Health and Consumers Directorate General is to make Europe’s citizens healthier, safer and more confident. Over the years the European Union has established EU laws on the safety of food and other products, on consumers' rights and on the protection of people's health. The DG Health and Consumers has the task of keeping these laws up to date.
It also ensures that the national, regional or even local governments in EU countries apply the EU's health and consumer protection laws and make sure traders, manufacturers and food producers in their country observe the rules.
